- the opaque or translucent region 204 may extend over the rest of the back wall 200 , or it may extend over only a portion of the rest of the back wall 200 , as a matter of design choice
- FIG. 4 is a perspective view of a fitment 400 (also referred to herein as an “insert assembly”) for the flexible container 100 .
- FIGS. 5 , 6 and 7 are respective top, front and side views of the fitment 400 .
- the fitment 400 includes a generally canoe-shaped mounting structure 402 , which includes a plurality of ribs 404 . Each rib 404 defines a bonding surface for sealingly bonding the fitment 400 to the interior of the flexible container 100 , about the opening 106 in the flexible container 100 , in a well-known manner.
- FIG. 8 is a front cut-away view of the fitment 400 installed in the flexible container 100 .
- a spout 406 is coupled to the mounting structure 402 .
- the spout 406 may be threaded to accept a complementarily threaded cap (not shown).
- the spout 406 defines a fluid channel 408 through the mounting structure 402 and into an interior 800 of the flexible container 100 .
- the spout 406 is in fluid communication with the interior 800 of the flexible container 100 .
- An axis 410 extends through the fluid channel 408 of the spout 406 .
- Two support structures 412 and 414 extend below the mounting structure 402 , generally parallel to the axis 410 . As can be seen in FIG. 8 , the support structures 412 and 414 extend into the interior 800 of the flexible container 100 , when the fitment 400 is installed in the flexible container 100 .
- the fitment 400 includes a grasp structure 416 , best seen in FIGS. 4 and 5 .
- the grasp structure 416 extends along a loop, i.e., along a closed curve whose initial and final points coincide in a fixed point.
- the loop is generally oral shaped.
- the loop has a major diameter at least about 11 ⁇ 2 times as long as a minor diameter of the loop.
- Four portions of the looped grasp structure are identified by reference numerals 416 in FIG. 5 .
- the loop lies generally in a plane 418 ( FIG. 4 ) that is generally perpendicular to the axis 410 , although the loop may include relatively minor undulations out of the plane 418 .
- the grasp structure 416 is attached to each of the support structures 412 and 414 .
- the grasp structure 416 extends proximate an inside perimeter of the flexible container, for example as indicated at 802 and 804 ( FIG. 8 ).
- the grasp structure 416 and, in some embodiments, the support structures 412 and 414 provide a skeletal structure against which the walls 102 and 200 may be pressed when a user grasps and squeezes or shakes the flexible container 100 .
- the flexible container 100 may define a waist portion 806 located a predetermined distance 808 from the opening 106 of the flexible container 100 .
- the waist portion 806 is narrower than vertically adjacent portions of the flexible container 100 .
- the mounting structure 402 , the support structures 412 and 414 and the grasp structure 416 are configured such that the grasp structure 416 is spaced from the mounting structure 402 along the axis 410 a distance approximately equal to the distance 808 . Consequently, the vertical position of the grasp structure 416 approximately corresponds with the vertical position of the waist portion 806 . This positioning allows the flexible container 100 to have portions (“shoulders” 810 and “hips” 812 ) that are larger, and therefore have greater capacities, than the waist portion 806 .
- the flexible container 100 may be grasped anywhere, the flexible container 100 exhibits better grasping performance, i.e., the walls 102 and 200 collapse less, when a user grasps the flexible container 100 about the waist portion 806 .
- a user grasps the flexible container 100 across the major diameter of the grasp structure 416 , as indicated schematically by arrows 420 ( FIGS. 4 and 5 ), or across the minor diameter of the grasp structure 416 , as indicated schematically by arrows 422 .
- the grasp structure 416 is relatively stiff, although it may resiliently deflect somewhat inward under urging of a user's grip.
- the grasp structure 416 may be dimensioned and/or made of a material selected to minimize or control the amount of deflection experienced by the grasp structure 416 or the amount of force required to deflect the grasp structure 416 when a user grasps the flexible container 100 .
- a first spacing member 424 may extend from a first point 426 along the grasp structure 416 to an approximately diametrically opposite point (not visible) along the grasp structure 416 .

Abstract
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 61/703,055, filed Sep. 19, 2012, titled “Insert Assembly for Beverage Container,” the entire contents of which are hereby incorporated by reference herein, for all purposes.
- The present invention relates to pouch-type flexible beverage containers (“pouches”) and, more particularly, to internal structures for such beverage containers to prevent collapse of the containers when grasped and/or to facilitate mixing ingredients within the containers.
- Liquids, such as beverages, detergents and pesticides, as well as many other liquids requiring airtight seals are packaged and contained in pouch-type containers. These containers typically include coverings or caps removably attached to opening portions, such as spouts, of the containers. A user can remove the cap from a container to access liquid contained therein and subsequently replace and reseal the cap to the container to maintain freshness of remaining liquid.
- Protein powder and other supplement drinks are popular among bodybuilders and other exercise enthusiasts. Typically, supplement powder and a liquid, such as water or milk, are mixed in a blender and then poured into a container for consumption, or the power and liquid are mixed within the container by shaking the container. Some supplement drink consumers prefer to consume such drinks within certain timeframes, such as within 60 minutes (a so-called “golden window”) after exercising.
- Many consumers prefer to keep supplement powder dry until they are ready to consume it. Thus, such consumers prefer to mix dry supplement powder with liquid just before they wish to drink the mixture. Several factors motivate delaying the addition of the liquid until just before the supplement is to be consumed. For example, cold liquid may be added to the powder, whereas a pre-mixed drink is likely to have warmed to an unappetizing temperature by the time a consumer is ready to drink it. Furthermore, pouches of dry powder are much lighter and less bulky than pouches that contain powder and liquid. In addition, some health-conscience consumers prefer not to purchase pre-mixed drinks, because pre-mixed drinks typically contain preservatives, and these consumers prefer to avoid these preservatives.
- Although some consumers purchase supplement powder in large, multi-serving containers and scoop a single serving quantity into their own beverage containers when needed, other consumers prefer to purchase single-serving pouch-type beverage containers that are pre-filled with dry supplement powder and add liquid just before consuming a drink. In either case, the supplement powder needs to be mixed with the liquid. However, most supplements do not mix well with water. For example, some supplements tend to clump, foam or fizz. Milk avoids most of the mixing problems. However, many consumers prefer to avoid calories that would be provided by the milk.
- Although pouch-type beverage containers have several advantages over rigid containers, pouch-type beverage containers become difficult to drink from as they become less than full. The pouch collapses, leaving little or nothing to solidly grasp, thereby making the containers awkward to drink from and difficult to shake, so as to mix supplement that has settled after an initial mixing. Furthermore, as the pouch collapses, it traps supplement in interior crevices and pockets and clinging to interior walls of the container. In some cases, a less-than-full pouch folds or flops, making it difficult to access some of the contents.
- An embodiment of the present invention provides a fitment for a flexible container. The flexible container has walls and defines an opening. The fitment includes a mounting structure, a spout coupled to the mounting structure, at least one support structure extending from the mounting structure and a grasp structure. The mounting structure is configured to be sealingly coupled to the flexible container about the opening, thereby defining an interior of the flexible container. The spout defines a fluid channel through the mounting structure. The spout is configured to be in fluid communication with the interior of the flexible container.

Embodiments of the present invention include fitments configured for insertion into pouch-type flexible containers and associated flexible containers.
- In some embodiments, the fitment includes a skeleton (also referred to herein as a grasp structure) within the pouch, against which flexible walls of the container can be pressed when a user grasps the outside of the pouch. The skeleton provides a structure against which the user can apply grasping force, thereby preventing significant collapse of the pouch. In some embodiments, the fitment includes structures that are spaced apart a distance approximately equal to an inside dimension of the pouch. The structures are configured to resist deflection toward each other.
- In some embodiments, the fitment includes a mixing structure that resides within the pouch and facilitates mixing contents, such as powders and liquids, in the pouch. The mixing structure interferes with smooth flow of the contents within the container, such as when the container is shaken or liquid is added to the container, thereby breaking up clumps of the powder and often creating turbulence in the liquid, which enhances mixing. The mixing structure does not, however, completely prevent flow of the contents within the container.

The opaque ortranslucent region 204 may extend over the rest of theback wall 200, or it may extend over only a portion of the rest of theback wall 200, as a matter of design choice -
FIG. 4 is a perspective view of a fitment 400 (also referred to herein as an “insert assembly”) for theflexible container 100.FIGS. 5 , 6 and 7 are respective top, front and side views of thefitment 400. Thefitment 400 includes a generally canoe-shapedmounting structure 402, which includes a plurality ofribs 404. Eachrib 404 defines a bonding surface for sealingly bonding thefitment 400 to the interior of theflexible container 100, about theopening 106 in theflexible container 100, in a well-known manner.FIG. 8 is a front cut-away view of thefitment 400 installed in theflexible container 100. - A
spout 406 is coupled to the mountingstructure 402. Thespout 406 may be threaded to accept a complementarily threaded cap (not shown). Thespout 406 defines afluid channel 408 through the mountingstructure 402 and into an interior 800 of theflexible container 100. Thus, thespout 406 is in fluid communication with the interior 800 of theflexible container 100. Anaxis 410 extends through thefluid channel 408 of thespout 406. - Two
support structures structure 402, generally parallel to theaxis 410. As can be seen inFIG. 8 , thesupport structures flexible container 100, when thefitment 400 is installed in theflexible container 100. - The
fitment 400 includes agrasp structure 416, best seen inFIGS. 4 and 5 . Thegrasp structure 416 extends along a loop, i.e., along a closed curve whose initial and final points coincide in a fixed point. In some embodiments, the loop is generally oral shaped. In some embodiments, the loop has a major diameter at least about 1½ times as long as a minor diameter of the loop. Four portions of the looped grasp structure are identified byreference numerals 416 inFIG. 5 . The loop lies generally in a plane 418 (FIG. 4 ) that is generally perpendicular to theaxis 410, although the loop may include relatively minor undulations out of theplane 418. - The
grasp structure 416 is attached to each of thesupport structures fitment 400 is installed in theflexible container 100, thegrasp structure 416 extends proximate an inside perimeter of the flexible container, for example as indicated at 802 and 804 (FIG. 8 ). Thegrasp structure 416 and, in some embodiments, thesupport structures walls flexible container 100. - For example, the
flexible container 100 may define awaist portion 806 located apredetermined distance 808 from theopening 106 of theflexible container 100. Thewaist portion 806 is narrower than vertically adjacent portions of theflexible container 100. The mountingstructure 402, thesupport structures grasp structure 416 are configured such that thegrasp structure 416 is spaced from the mountingstructure 402 along the axis 410 a distance approximately equal to thedistance 808. Consequently, the vertical position of thegrasp structure 416 approximately corresponds with the vertical position of thewaist portion 806. This positioning allows theflexible container 100 to have portions (“shoulders” 810 and “hips” 812) that are larger, and therefore have greater capacities, than thewaist portion 806. - Although the
flexible container 100, with thefitment 400 installed, may be grasped anywhere, theflexible container 100 exhibits better grasping performance, i.e., thewalls flexible container 100 about thewaist portion 806. Typically, a user grasps theflexible container 100 across the major diameter of thegrasp structure 416, as indicated schematically by arrows 420 (FIGS. 4 and 5 ), or across the minor diameter of thegrasp structure 416, as indicated schematically byarrows 422. - The
grasp structure 416 is relatively stiff, although it may resiliently deflect somewhat inward under urging of a user's grip. Thegrasp structure 416 may be dimensioned and/or made of a material selected to minimize or control the amount of deflection experienced by thegrasp structure 416 or the amount of force required to deflect thegrasp structure 416 when a user grasps theflexible container 100. - A first spacing member 424 (best seen in
FIG. 4 ) may extend from afirst point 426 along thegrasp structure 416 to an approximately diametrically opposite point (not visible) along thegrasp structure 416. For example, thefirst spacing member 424 may extend across a minor diameter of thegrasp structure 416. Thefirst spacing member 424 stiffens thegrasp structure 416 along the minor diameter of thegrasp structure 416. Thefirst spacing member 424 may be dimensioned and/or made of a suitable material selected to minimize or control the amount of deflection experienced by thegrasp structure 416 when a user grasps theflexible container 100. - The
first spacing member 424 may be straight or, as shown inFIG. 4 , thefirst spacing member 424 may extend generally along an arc in a plane generally perpendicular to theplane 418 of theloop 416. As can be seen inFIG. 7 , the arc of thefirst spacing member 424 is not necessarily a smooth arc, i.e., the arc may include a point, such as at the top of the arc, where two smooth arcs join. Thefirst spacing member 424 is not directly attached to the mountingstructure 402. However, thefirst spacing member 424 is indirectly attached to the mountingstructure 402, i.e., via thegrasp structure 416 and thesupport structures - To provide tactile feedback and a surer grip, two
pads grasp structure 416 at the two points 426 (and not visible) where the spacingmember 424 is attached to thegrasp structure 416. Thepads axis 410 and, more specifically, parallel to thewalls flexible container 100. The twopads pad features 430 and/or a depression 432 for tactile feedback and better grip. - The
support structures grasp structure 416 at tworespective points 434 and 436 (best seen inFIG. 6 ) located on thegrasp structure 416 approximately equidistantly between the two points 426 (and not visible) where the spacingmember 424 attaches to thegrasp structure 416. - Each
support structure concave portion 438 and 440 (best seen inFIG. 6 ). Theseconcave portions 438 and 440 provide tactile feedback and surer grip. - A second spacing member 425 (best seen in
FIG. 4 ) may extend from where thefirst support structure 412 is attached to thegrasp structure 416 to where thesecond support structure 414 is attached to thegrasp structure 416. For example, thesecond spacing member 425 may extend from thepoint 434 on thegrasp structure 416 to thepoint 436 on thegrasp structure 416. The points where thesecond spacing member 425 attaches may be approximately diametrically opposite each other, with respect to the loop of thegrasp structure 416. Thesecond spacing member 425 stiffens thegrasp structure 416 along the major diameter of thegrasp structure 416. Thesecond spacing member 425 may be dimensioned and/or made of a suitable material selected to minimize or control the amount of deflection experienced by thegrasp structure 416 when a user grasps theflexible container 100. - The
second spacing member 425 may be straight or, as shown inFIGS. 4 and 8 , thesecond spacing member 425 may extend generally along an arc in a plane generally perpendicular to theplane 418 of theloop 416. As can be seen inFIG. 8 , the arc of thesecond spacing member 425 may be smooth. However, in other embodiments, the arc may not necessarily be smooth, i.e., the arc may include a point, such as at the top of the arc, where two smooth arcs join. Thesecond spacing member 425 is not directly attached to the mountingstructure 402. However, thesecond spacing member 425 is indirectly attached to the mountingstructure 402, i.e., via thesupport structures grip structure 416. - The
flexible container 100 may have a predetermined internal depth 814 (FIG. 8 ). The mountingstructure 402, thesupport structures grasp structure 416 may be configured such that, when thefitment 100 is installed in theflexible container 100, thegrasp structure 416 is spaced from the mountingstructure 402 along the axis 410 adistance 816 that is between about ¼ and ¾ theinternal depth 814 of theflexible container 100. In some embodiments, thedistance 816 is about ⅓ of theinternal depth 814. Thedistance 816 may be approximately equal to thedistance 808 thewaist portion 806 is located below the top of theflexible container 100. - The
fitment 400 may be molded of a polymeric or other suitable material or fabricated by another suitable process. Exemplary polymeric materials include polypropylene, polystyrene, polystyrene-acrylonitrile, acrylonitrile-butadiene-styrene, styrene-maleic anhydride, polycarbonate, polyethylene terephthalate, polyvinyl cyclohexane and blends thereof. - Some embodiments of the
fitment 400 include a mixing structure, with or without agrasp structure 416. This description is of afitment 400 that includes agrasp structure 416 and a mixing structure. However, other embodiments may omit thegrasp structure 416. Similarly, some embodiments include agrasp structure 416, without a mixing structure. - A mixing structure 600 (best seen in
FIG. 6 ) includes a plurality of members, exemplified bymembers 602, 604 and 606, that are interconnected and collectively define a plurality of apertures, exemplified byapertures structure 600. In the embodiment illustrated inFIGS. 4-8 , the mixingstructure 600 resembles an open-weave basket with generally rectangular apertures 608-612, however other shaped members and other shaped apertures may be used. The members 602-606 act to break up clumps of powder, when fluid is introduced into theflexible container 100 or thecontainer 100 is shaken. - The first and
second spacing members structure 600. In the embodiment shown inFIGS. 4-8 , the first andsecond spacing members structure 600. Thus, material used to make up the first andsecond spacing members spacing members structure 600. - The mixing
structure 600 is mechanically coupled to the mountingstructure 402 by thesupport structures structure 600 is configured to be disposed in the interior of theflexible container 100, as shown inFIG. 8 . The mixingstructure 600 is disposed, relative to the mountingstructure 402, so as to interfere with smooth flow of fluid introduced through thespout 406 in a direction toward the interior 800 of theflexible container 100. For example, as a stream of fluid is introduced through thespout 406, at least a portion of the stream comes into contact with the members 602-606 of the mixingstructure 600, creating turbulence in the stream, thereby promoting mixing of the fluid with powder in theflexible container 100. - As noted, the
flexible container 100 may have a predetermined internal depth 814 (FIG. 8 ). The mountingstructure 402, thesupport structures structure 600 may be configured such that, when thefitment 100 is installed in theflexible container 100, the mixingstructure 600 is spaced from the mountingstructure 402 along the axis 410 a distance 818 that is between about ¼ and ¾ theinternal depth 814 of theflexible container 100. In some embodiments, the distance 818 is about ⅓ of theinternal depth 814. The distance 818 may be approximately equal to thedistance 808 thewaist portion 806 is located below the top of theflexible container 100. - As noted, the back wall 200 (
FIG. 2 ) of theflexible container 100 defines a generallyoval window 206. Thewindow 206 is sized and located on theback wall 200 to generally coincide with the size and location of the mixingstructure 600. Thus, a user can see the mixingstructure 600 and ascertain whether a significant amount of powder is adhered to the mixingstructure 600. If so, the user may further shake theflexible container 100 to dissolve the adhered powder or disperse it into suspension in the fluid in theflexible container 100. - The
pads 428 and 430 (FIGS. 5 and 7 ) may also be visible through thewindow 206. In some embodiments, theconcave portions 438 and 440 of thesupport structures window 206. These visibilities provide visual cues to a user where and how to grasp theflexible container 100. - As can be seen in
FIG. 8 , the mountingstructure 402, thesupport structures structure 600 are configured such that the mixingstructure 600 is spaced from the mountingstructure 402 along the axis 410 a distance approximately equal to thedistance 808. Consequently, the vertical position of the mixing structure 800 approximately corresponds with the vertical position of thewaist portion 806 of theflexible container 100. -
FIG. 9 illustrates, in partial sectional view, acontainer assembly 900, according to one embodiment. Thecontainer assembly 900 includes acontainer 910 and an insert assembly orfitment 912 configured to provide both fluid entry and fluid removal from thecontainer 910. For example, thecontainer 910 can be configured as a single serving pouch defining aninternal volume 914 that contains apowdered material 916, such as a powdered drink concentrate or a protein powder. Theinsert assembly 912 defines a single opening 18 that provides fluid communication between theinternal volume 914 and the outside of thecontainer 910 for both addition and removal of fluid relative to thecontainer 910. While theopening 918 defined by theinsert assembly 912 can be configured in a variety of ways, in one arrangement, theopening 918 is sized and shaped to receivefluid 920, such as water from an external source, and to direct the fluid to thepowdered material 916 contained within theinternal volume 914. - The
insert assembly 912 is also configured to agitate the fluid 920 as it enters thecontainer 910, thereby causing the fluid 920 and thepowdered material 916 to mix with each other. For example, theinsert assembly 912 includes a flow-throughstructure 922 extending into theinternal volume 914 of thecontainer 910 and substantially aligned with alongitudinal axis 924 of theinsert assembly 912. As a user addsfluid 920, such as water, to thecontainer 910 via theopening 918, the fluid 920 flows through and/or past the flow-throughstructure 922 which, in turn, agitates or induces turbulent flow in thefluid 920. As the turbulent fluid exits the flow-throughstructure 922, the fluid 920 mixes with thepowdered material 916 contained within theinternal volume 914. Once mixed, the user can then drink the mixture from thecontainer 910 via theinsert assembly 912. - While the
insert assembly 912 can be manufactured in a variety of ways utilizing a variety of materials, in one embodiment, a manufacturer injection molds theinsert assembly 912 from a suitable plastic material. The manufacturer can then secure theinsert assembly 912 to thecontainer 910 utilizing a variety of fixation materials and methods, as are well known in the art. -
FIG. 10 illustrates an example of acontainer assembly 1000, in partial sectional view, that includes a container 1010 and aninsert assembly 1012. The container 1010, as illustrated, is configured as a bag or pouch. For example, the pouch can be manufactured from a flexible or compliant material, such as a thin plastic film material, or foil film.Insert assembly 1012 includes a mountingelement 1013, a graspingassembly 1017, aspout element 1015 carried by the mountingelement 1013, and a flow-throughstructure 1022 carried by the mountingelement 1013 and disposed in fluid communication with thespout element 1015. - The mounting
element 1013 is configured to be coupled to the container 1010. For example, as illustrated inFIG. 10 , the mountingelement 1013 is disposed at acorner 1025 of the container 1010. In one arrangement, the mountingelement 1013 is configured to maintain a distance between, or separation of, at least a portion of the lateral walls of the container 1010, namely afirst wall 1027 and an opposing second wall 1029. For example, when the container 1010 is configured as a pouch formed of a compliant material, the mountingelement 1013 maintains a separation between thewalls 1027, 1029 of the container 1010 at least in proximity to the mounting element. Such separation allows thewalls 1027 and 1029 to define thevolume 1014 within the container 1010 and to allow a user to readily and easily introduce fluid into the container 1010. While the mountingelement 1013 can be configured as a wedge or diamond shape, as indicated inFIG. 19 , it should be noted that the mountingelement 1013 can be configured in a variety of other shapes as well. - The grasping
assembly 1017 is configured to provide a level of rigidity to the container 1010 to allow a user to readily grasp and hold the container 1010. For example, the graspingassembly 1017 can include a firstgrasping element 1050 extending longitudinally from the mountingelement 1013 and a secondgrasping element 1052 extending longitudinally from a distal portion of the flow-throughstructure 1022. In use, a user can grasp the container 1010 along a direction that is substantially parallel towalls 1027 and 1029 to engage the first and secondgrasping elements - The
spout element 1015 is configured to allow fluid to both enter and exit thevolume 1014 of the container 1010. For example, thespout element 1015 defines anopening 1018 that extends along alongitudinal axis 1024 of theinsert assembly 1012 between a location outside of the container 1010 and thevolume 1014 defined by the container 1010. In one arrangement, thespout element 1015 includes a set ofexternal threads 1026 disposed about an outer perimeter of thespout element 1015. The set ofthreads 1026 is configured to interface with a corresponding set of complementarily-shaped internal threads of an associated cover orcap 1028. Interaction between the set ofexternal threads 1026 on thespout element 1015 and the set of internal threads of thecover 1028 provides a releasable seal between thecover 1028 and the container 1010. - The flow-through
structure 1022 extends from the mountingstructure 1013 into thevolume 1014 defined by the container 1010. While the flow-throughstructure 1022 can extend into thevolume 1014 in a variety of ways, in one arrangement as illustrated inFIG. 10 , the flow-throughstructure 1022 extends substantially perpendicular to the mountingstructure 1013 and at anangle 1030, such as about 45°, relative to ahorizontal reference 1032 associated with the container 1010. - As indicated above, the flow-through
structure 1022 is configured to induce turbulence to fluid added to the container 1010 as the fluid flows from thespout element 1015, past the flow-throughstructure 1022, and to thecontainer volume 1014. While the flow-throughstructure 1022 can be configured in a variety of ways, as illustrated inFIGS. 11 , 14, and 15, the flow-throughstructure 1022 includes a series of steps orladder elements 1034 extending between a first andsecond support step elements 1034 are disposed at substantially a 90° angle relative to a flow direction of a fluid 1020 entering the container 1010. As the fluid 1020 contacts the series ofstep elements 1034, thestep elements 1034 impinge upon at least a portion of the flow of the fluid 1020 to create turbulence within the fluid stream. As the turbulent fluid contacts the powdered material 1016 disposed within the volume, the turbulence causes mixing of the fluid with the powdered material 1016. - Based upon the configuration of the flow-through
structure 1022, the insert provides substantially automatic mixing of the fluid 1020 and a powdered material 1016 disposed within a container 1010. -
FIGS. 16-19 illustrate another embodiment of aninsert assembly 1212 for a container. For example, theinsert assembly 1212 includes a mountingelement 1213, a graspingassembly 1217, aspout element 1215 carried by the mountingelement 1213, and a flow-throughstructure 1222 carried by the mountingelement 1213 and disposed in fluid communication with thespout element 1215. - The grasping
assembly 1217 is configured to provide a level of rigidity to an associated container to allow a user to readily grasp and hold the container. For example, the graspingassembly 1217 can include a firstgrasping element 1250 and a secondgrasping element 1252 disposed at a proximal end of the flow-throughstructure 1222. In use, in the case where the container is configured as a pouch, a user can grasp, as schematically indicated by arrows 1262 (FIG. 19 ), the associated container along direction that is perpendicular to the walls of the pouch to engage the first and secondgrasping elements assembly 1217. However, alternatively, the user may grasp the container across a major diameter of the graspingassembly 1217, as indicated byarrows 1263. - As illustrated, the flow-through
structure 1222 is configured as a basket structure. For example, the flow-throughstructure 1222 includes substantiallylateral structures 1234 that extend from the graspingassembly 1217 as well aslongitudinal structures 1235. With such a configuration, the lateral andlongitudinal structures spout element 1215 to create turbulence within the fluid. - Also as illustrated, the flow-through
structure 1222 is disposed at a distance from the mountingstructure 1213 by asupport structure 1270. For example, thesupport structure 1270 is configured as a set ofsupports 1271 that extend longitudinally from the mountingstructure 1213 and that couple to a distal end of the flow-throughstructure 1222. Further, the flow-throughstructure 1222 can be disposed within a container at a variety of distances from a top or upper surface of the container. For example, in one arrangement, the flow-throughstructure 1222 is disposed from the top surface of the container at a distance of approximately ⅓ a total length of the container. Such positioning can optimize mixing of a fluid introduced to the container with a powdered material carried therein. -
FIGS. 20-23 illustrate another embodiment of aninsert assembly 2312 for a container. Theinsert assembly 2312 includes a mountingelement 2313, a graspingassembly 2317, aspout element 2315 carried by the mountingelement 2313, and a flow-throughstructure 2322 carried by the mountingelement 2313 and disposed in fluid communication with thespout element 2315. - As illustrated, the flow-through
structure 2322 is configured as a grid or mesh structure. For example, the flow-throughstructure 2322 includes substantiallylateral structures 2334 andlongitudinal structures 2335 that extend within the graspingassembly 2317. With such a configuration, the lateral andlongitudinal structures - The flow-through
structure 2322 is disposed at a distance from the mountingstructure 2313 by asupport structure 2370. For example, thesupport structure 2370 is configured as a set of flaredsupports 2371 that extend longitudinally from the mountingstructure 2313 and that couple to the graspingassembly 2317. Further, the flow-throughstructure 2322 can be disposed within a container at a variety of distances from a top or upper surface of the container. For example, in one arrangement the flow-throughstructure 2322 is disposed from the top surface of the container at a distance of approximately ⅓ a total length of the container. - As indicated above, when a user adds fluid to a container via an insert assembly, the fluid contacts an associated flow-through structure which creates turbulence within the fluid stream and causes mixing of the fluid with powdered material carried within the container. However, in certain cases the powdered material may not completely mix with the fluid introduced to the container. As a result, the resulting mixture can include clumps of non-dissolved powder that can be consumed by the user. To minimize the delivery of clumps of non-dissolved powder to the user, in one arrangement, the insert assembly includes a particle filter configured to limit or prevent the clumps from entering the spout element of an associated insert assembly.
- For example,
FIGS. 24-27 illustrate another arrangement of aninsert assembly 3412 for a container where theinsert assembly 3412 includes a particle filter 3425. While the particle filter 3425 can be configured in a variety of ways, in one arrangement, the particle filter 3425 is configured as a set ofslat elements 3427 extending laterally between a mountingstructure 3413 and a flow-throughstructure 3422. In one arrangement, theslat elements 3427 define a substantially tube-shaped structure substantially aligned with anopening 3418 of an associatedspout element 3415. While the set ofslat element 3427 can be disposed at a variety of relative spacings, in one arrangement, each slat element is disposed at a distance 3429 (FIG. 25 ) of about 3 mm form each other. With such spacing, the particle filter 3425 can limit or prevent delivery of clumps of non-dissolved powder to the user. - With continued reference to
FIGS. 24-27 , the insert assembly is configured with a firstgrasping assembly 3417 and a secondgrasping assembly 3419. For example, the first graspingassembly 3417 extends substantially longitudinally from the flow-throughstructure 3422 and includes opposing first and secondgrasping elements grasping assembly 3419 also extends substantially longitudinally from the flow-throughstructure 3422 and includes opposing first and secondgrasping elements grasping elements grasping elements - While
FIGS. 24-27 illustrate theinsert assembly 3412 as including both first and second graspingassemblies FIG. 28 , theinsert assembly 3412 includes only the secondgrasping assembly 3419. As shown inFIG. 29 , with such a configuration, the user can grasp the associated container 3405 along an axis that is parallel to the walls to engage the first and secondgrasping elements walls 3427 and 3429 to engage the first and secondgrasping elements - While
FIGS. 24-27 illustrate an arrangement of aninsert assembly 3413 including both a flow-throughstructure 3422 and a particle filter 3425, such illustration is by way of example only. In one embodiment illustrated inFIG. 30 , an insert assembly 4512 is configured as having only a particle filter 4525 extending from an associated mounting structure 4513. As described above, the particle filter 4525 is configured to limit or prevent the non-dissolved clumps of powder from entering thespout element 4515 of the insert assembly 4512. -
FIGS. 31-34 illustrate an alternate embodiment of an insert assembly. As illustrated, the insert assembly 5512 includes the particle filter 5525 having a graspingassembly 5517 attached thereto. For example, the graspingassembly 5517 includes a firstgrasping element 5550 coupled to a distal end of the particle filter 5525 via afirst arm 5560 and a second opposing graspingelement 5552 coupled to the distal end of the particle filter 5525 via a second arm 5562 (FIG. 32 ). While thegrasping elements FIG. 33 , thegrasping elements walls FIG. 34 , the user grasps the container 5505 via the grasping elements 552, 554 along a direction that is substantially perpendicular to thewalls 527, 529 of the container 505. The user can then add fluid to the container 505 and shakes the container 5505 using an up-and-down or a side-to-side motion, as indicated by two-headedarrow - While various embodiments of the innovation have been particularly shown and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the innovation as defined by the appended claims.
- For example, as indicated above, the insert assembly includes a flow-through structure configured to mix the powder and fluid when a user agitates or shakes the container. As indicated above, the flow-through structure may be configured as a ladder structure (
FIGS. 11 , 14, and 15) or as a mesh. Such indication is by way of example only. In one arrangement, the flow-through structure can be configured with a variety of shapes. For example, the flow-through structure can be configured as a helical shape or structure. - As indicated above, with reference to
FIG. 9 , thecontainer 900 can be configured as a single serving pouch defining aninternal pouch volume 914 that contains apowdered material 916, such as a powdered drink concentrate, baking product or a protein powder. It should be noted that thepowdered material 916 can be added to thecontainer 900 at any time prior to a user mixing a drink. For example, in one arrangement, thepowdered material 916 can be added to thecontainer 900 by a manufacturer prior to distribution of thecontainer 900 to consumers. In another arrangement, after purchasing anempty container 900, i.e. withoutpowdered material 916, the user can add powdered concentrate to thecontainer 900 prior to or after adding fluid. - In another embodiment, the
container 900 is prefilled by a manufacturer with liquid, and a user can then add power and mix the combination prior to consuming or otherwise using the mixture. - In another embodiment, the
container 900 includes two or more burstable compartments that are not in fluid communication with each other. Each compartment may contain a different liquid or powder. A user can then squeeze thecontainer 900 to rupture one or more internal walls separating the compartments, thereby allowing the contents of the compartments to be mixed, such as by shaking thecontainer 900. -
